SPECIFICATION forming part of Letters Patent No. 762,437, dated June 14- 1904.

Application filed June 1,1903. Serial No. 159,527. (No model.)

To (1, whom, it may concern: 7

Be it known that I, HOWARD PARKER, a citizen of the United States of'America, residing at Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Paper Making Machinery, of which the following is a specification.

This improvement relates to that class of paper-making machinery in which the pulp held in suspension in a liquid in a tank is formed into a web on the cylinder-mold and from this web is taken onto a couch or press roll and is taken ofi' from this couch-roll by what is known as adoctor.

The invention relates particularly to the construction of the doctor.

The drawing represents a side elevation of a machine embodying my invention made in section to illustrate the construction.

(1 denotes the tank, 6 the cylinder-mold therein, and c a roll coacting with the cylinder-mold. This roll 0 is provided with what is known as a paper-makers jacket, which causes the Web of pulp on the cylinder-mold to adhere to it.

(Z is a doctor which removes the pulp from the surface of the roll 0 and in the case illustrated deposits it in a tank a. This doctor has a foraminous top, as indicated at g, and preferably is provided at its under side with a receptacle of some sort, as the box it, having an outlet 29.

Any excess of water which is taken off the roll c by the doctor will pass down through the top 9 into the box it and be carried off through the pipe p.

I claim as my invention- 1. A doctor having a foraminous top.

2. A doctor having a foraminous top and a receptacle formed on its side.

In testimony whereof I afiix my signature in presence of two witnesses.

HOWARD PARKER.
